New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could ...

98.5% of the Sun is made up of two light chemical elements, hydrogen and helium, while the remaining 1.5% consists of other heavier elements such as carbon, oxygen, and iron. The abundance of these ...

The study of stellar astrophysics and galactic structure investigates the life cycles of stars and the organisation of galaxies. At its core, the field explores how stellar evolution, from the ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become ...

Astronomers believe this barred spiral galaxy could be the oldest example of its kind ever observed. Research led by Daniel ...
